' To all whom it may concern:

Be it known that 1, Earn. N. Psncr, citizen of the United. States,residing in the city and county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Oil-GasApparatus, of which the followin is a specification.

My invention re ates to a means for obtaining gas of that class known asproducer gas from the combined action of an incandescent Carboniferousfuel, and a spray or jet of ignited oil directed upon and through saidfuel.

It also consists in details which will be more fully explained in thefollowing specification. p

The figure is a vertical sectional view of an oil gas apparatus showingmy invention.

My invention is desi ned to first burn the oil or liquid hydrocarboneither wholly or vpartially, and to pass the products of comustion,which accompanying heat, over or through the solid Carboniferous fuel,which may consist of coke, charcoal, or under cer tain conditions,lignite, peat, wood, or anything which will carbonize, and to formlayers of incandescent carbon for the prod nets of combustion of the oilto pass through.

- Such a gas is similar to producer gas, WlllCll is evolved from coalconsiderabl richer.

In carrying out my invention the oil is burned in conjunction with air,and if desired, steam may also be employed.

As shown in the drawing, A is a stack or chamber containing in the lowerpart a carboniferous fuel 2. At the top of the stack is a closure 3,through the. center of which enters an oil discharge pipe 4. Exterior tothis pipe are air and steam inlet pipes, as 5 and 6, and the lower endis made divergent or funnel-shaped, as shown. at 7. Oil being admittedthrough the inlet pipe is ignited and discharged in a divergent jet orspray, being burned as it passes downwardly, and strikes the top ofthecarboniferous fuel which is soon ignited and raised to anincandescent state.

The products of combustion of the oil consist of carbonic acid gas (C0,)and other gases, and these gases pass through the ayers of fuel which isthus rendered incan descent. As the CO, passes through this carbon ittakes up another atom of carbon and becomes carbonic oxid (G0) which isgas producers, but is wardly thercinto; and air and steam a combustiblegas. If steam be admitted it acts in a well known manner to enrich thegas with free hydrogen and more carbonic oxid, and furthermore, preventsclinker from forming.

If the combustion of the oil is incomplete, the unburned parts will bedelivered at a point where the flame impinges,in the form of particlesof oil, tar, lampblack, and other heavy constituents. Under theinfluence of the heat these will all be reduced to lampblack, coke,vapor, gases, and clinker, and tend in a measure to replace the cokewhich furnishes the additional atom. of carbonto unite with the carbonicacid gas, and oxygen produced by the steam. The gases and products ofthis operation pass through the fuel bed, coming out at the bottom aspermanent gases, clinker, and a small amount of free carbon andcondensable vapors. The gas after leavin the apparatus is washed andpurified, an is intended primarily for gas engines, furnaces, etc., butmay be subjected to special treatment to lit it for illuminatingpurposes.

This invention may be employed in either a suction or a pressureapparatus. Any suitable provision may be made for feeding the solid fuelwithout letting in fresh air, and also for removing clinker, ash, andother debris.

Patented at... s, 1910 In the drawing, the closure 3 is in theform of ahopper or container having the lower part convergent to meet thedivergent funnel 7. This; container has a removable cover or openingthrough which it may be charged, and a ate 1n the lower part throughwhich SOlltlfllQl may be admitted into the main chamber A, as required;

Having thus described my inventiomwhat I claim and desire to secure byLetters Patcut is-- An apparatus forunanufacturing gas, said apparatuscomprising a retort having a vertical chamber with a gas outlet at thebottom; :1 solid fuel hopper at the-top, having a lower cone-shaped endentering the top of said chamber, said hopper having a central tubularportion whose lower end diverges downwardly; an oil supply pipe passingthrough said tubular portion of the hopper and adapted to discharge adivergent spray into the top of said chamber and down entering thecentral tubular portion 0 the pipes hopper and dischar ing in the saiddivermy hand in the presence of two subscribihg gent portion theme injuxtaposition with witnesses.
